This set of bushings and studs is made from high-quality carbon steel and processed with blue-white zinc plating technology. It combines excellent mechanical strength with remarkable corrosion resistance, making it suitable for humid and complex working conditions. The bushings feature smooth inner walls and precise dimensions, while the studs have stable thread engagement. These components support coordinated application with stainless steel parts and cover diverse assembly requirements, providing reliable connection support for mechanical assembly, equipment maintenance, and more. Widely used in machinery manufacturing, auto parts, and electronic equipment industries.

• Reliable Material: Carbon steel base material ensures mechanical strength, while the dense, uniform blue-white zinc coating effectively resists corrosion and extends equipment maintenance cycles.
• Precision Control: Advanced processing equipment and strict quality control ensure precise inner diameters for bushings and tight tolerances for studs, reducing assembly errors and improving production efficiency.
• Diverse Scenarios: Standard parts meet regular needs while supporting customized development (dimensions, coatings, etc. can be adjusted as needed) for special industrial applications.
